Examples

Upsert your data

• JavaScript

const { data, error } = await supabase

.from('messages')

.upsert({ id: 3, message: 'foo', username: 'supabot' })

Upserting into tables with constraints

Running the following will cause supabase to upsert data into the users table. If the username 'supabot' already exists, the onConflict argument tells supabase to overwrite that row based on the column passed into onConflict.

• JavaScript

const { data, error } = await supabase

.from('users')

.upsert({ username: 'supabot' }, { onConflict: 'username' })

Return the exact number of rows

• JavaScript

const { data, error, count } = await supabase

.from('users')

.upsert({

id: 3, message: 'foo',

username: 'supabot'

}, {

count: 'exact'

})
